Britain's great energy debate

The UK faces some tough choices on its energy policy future in the coming years and decades. The rise of wind, wave, tidal, solar, biogas and other renewable options is rubbing up against an ongoing reliance on oil, gas and coal, while nuclear remains an option the government continues to adopt an uncertain approach to. Fracking for shale gas is also being considered carefully. As the next general election begins to loom over the horizon, the debate over where our electricity comes from is starting to hot up - and nothing seems guaranteed.

May 1979, the election that brought to power the government that led to the miners' strike, was a vote of huge change. In May 2015, Britain once again has the opportunity to vote. And once again the status quo is breaking apart.
